Charles H. Spurgeon on Psalms 55:19

They fear not God. The fear required here, is to fear him as God, and as God presented in this name, Elohim; which though it be a name primarily rooted in power and strength (for El is Deus fortis, The powerful God; and as there is no love without fear, so there is no fear without power), yet properly it signifies his judgment, and order, and providence, and dispensations and government of his creatures. It is that name which goes through all God's whole work of the creation, and disposition of all creatures in the first of Genesis: in all that he is called by no other name than this, the name God; not by Jehovah, to present an infinite majesty; nor by Adonai, to present an absolute power; nor by Tzebaoth, to present a force, or conquest; but only the name of God, his name of government. All ends in this; to fear God is to adhere to him, in his way, as he hath dispensed and notified himself to us; that is, as God is manifested in Christ, in the Scriptures, and applied to us out of those Scriptures, by the church: not to rest in nature without God, nor in God without Christ. John Donne, 1573-1631.
